Reminders do not synch

Hello! After installing the latest WatchOS 6.1 on my Series 2 watch, the Reminders app stopped syncing with the Reminders app on the iPhone. I tried to delete Reminders from the phone, restarted both devices and even unpaired the watch and created a new pair (not from a backup copy). I receive notifications from Reminders, but cannot normally control them. I do not see any reminders in the Watch app nor can I create any reminders from the watch. Everything worked fine on WatchOS 5. Is it a new bug? Have you encountered such problem?
